Hey EL, I put the 3.55s in my 96 GTS and I love them!! My car is modded about the same as yours, and you will see a bigger improvement in pull , more than all of your mods put together. The car pulls real hard in 2nd, traction may be a problem, but you can practice the launch and overcome it. I live in CT and its kinda like NY, its hard to find a long open spot, the gears will get you around better in tighter driving arenas...AL...00PROWLER...
